Research on the effects of declining abundances of the Eastern oyster (Crassostrea virginica) in Chesapeake Bay and other estuaries has primarily focused on the role of oysters in filtration and nutrient dynamics, and as habitat for fish or fish prey. Oysters also play a key role in providing substrate for the overwintering polyp stage of the scyphomedusa sea nettle, Chrysaora quinquecirrha, wh...

Growing environmental concerns are becoming significant challenges for large-scale applications in the automotive industry. Replacing and hybridizing glass fibers with natural non-structural is one effective way to address this challenge, while retaining useful properties of both. This paper investigates mechanical damping performance four types compression-molded materials: polyester matrix (r...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Benign Prostatic Hyperplasia (BPH) is a common disease observed in 90 percent of men over 60 (1). Benign prostat-ic hyperplasia is the most common benign tumor in men (2). The exact cause of this disease is still unknown, and environmental and genetic causes are thought to...

Chrysciova quinquecirrha, the common sea nettle infests the Chesapeake Bay waters during the summer season. This coelenterate causes a severe economic problem for this resort area because of the painful sting it iaflicts upon bathers who accidentally come in contact with its tentacles. These stings are thought to result from the injection of nematocyst threads and the introduction of a toxin in...

background and objective: nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. medicinal plants are also of great importance as antibacterial agents. therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of net...

Nettle, Stinging Nettle (Common names) Urticadioca; Urticaurens (Scientific is considered by many to be a bothersome pest, but the nettle has been used since ancient times as source of food, fiber, and medicinal preparations. They also called in commonly nettle, weedy perennial plant family (Urticaceae). It known for its stinging leaves classified eukaryote. Because they contain true nucleus me...

Nettle et al. [1] explored the conditions under which it could be adaptive for humans to calibrate the development of life history traits (for example, reproductive timing) on the level of adversity experienced in early life. They concluded that external predictive adaptive responses (PARs)—in which early cues are employed to forecast the adult environment—can only evolve if environmental state...

background: cutaneous reactions like pruritus and erythema are common in warm months of the year in bushehr port, persian gulf, iran due to jellyfish envenomation. this study reports isolation of the chrysaora hysoscella nematocysts and evaluating its pharmacological activities during a bloom in 2013. methods: the venom of c. hysoscella captured in jofre area in bushehr port was analyzed. the e...
